I've looked through many resources and pulled out what I felt was the best pieces of information and put it all together in this article. The first two sections are on measuring and building your own 4-link.

These articles are all over the internet and were written by Fred Williams at 4Wheel & Off-Road Magazine (www.4wheeloffroad.com). I've seen a lot of good tech on the net come and go over the years, so I've preserved his articles here to ensure they're not lost. Four-Link Tech - Part 1 What Is a Four-link? A four-link suspension uses links to locate the axle from moving side to side and front to back, while allowing it to travel up and down and articulate. Considerations Till then you have a bit of homework. Now plot a point on the front center of the rear axletube.

In powered axles, gears that deliver torque from the drive shaft to the left and right axle half - shafts separately. They allow the left and right wheels to turn at different road speeds when turning (thus the term "differential"), so that neither wheel has to scuff. Conventional "open" differentials tend to equalize the torque delivered through both wheels.

Thus if one wheel loses traction - "spins out" on snow, mud, sand, or gravel - it delivers very little power to the ground (power = torque x RPM, so if torque goes to 0, so does power). The other wheel will deliver only the same very torque as the spinning wheel and if this is not enough to overcome the inertia and static friction holding the verhicle in place, you are stuck.

In an open differential, the following rule applies: The average speed of the two axles is equal to the speed of the ring gear. Spool Locking Automatic Manual Limited Slip Friction/clutches Geared.

The Wrangler is a direct descendant of the World War II Willys MB by way of the Willys civilian Jeeps (Jeep CJ) of the mid-1940s through 1980s, later produced by Kaiser-Jeep and by American Motors (AMC). Just like their predecessors, the Willys MB and the Jeep CJ, Wranglers continue to use a separate body and frame, rigid live axles both front and rear, a fold-flat windshield, and can be driven without doors. The Wrangler debuted in 1986 as a revision of the Jeep CJ-7, was revised in 1996, and completely redesigned in 2006. In addition to the nameplate Wrangler, each model received a designation corresponding to its generation: YJ (1986–1995), TJ (1997–2006), LJ's (2003–2006 Unlimited models) and JK (2007–present).
